I cried. I feel like I did everything humanly possible, so I felt discouraged. I'm sure you were upset as well. Do you mean you are using the same device that gave you trouble today?
As stated, the system check didn't give an accurate prediction for test day, so that's why I hope to find a device that has proven successful on a test day. I value privacy myself, but this is the best I could do in this urgent situation.
I think they (LSAC) don't want anyone reading aloud (softly or loudly), because they don't want some recording device in another room / out of sight of the camera room check capturing content and making a record of the test questions.
